- The through movement passenger car equivalents (pcphpl) for each approach of Vine and Maple Streetsintersections obtained from a traffic survey as shown in the following diagram. Vine Street for NSmovements 1s 48 ft wide and Maple Street for EW movements is 60 ft wide. There are two throughmovement lanes and one left-tum lane in each approach. The yellow times for Vine Street and MapleStreet through movement and left-tum phases are 4 second and 3 seconds per g_hase, respectively. TheAll-red for each phase is 2.0 seconds and the ost time is 5 seconds per phase. Pedestrian walkmgspeed is 3.5 ft/sec. Assuming equal distribution of traffic on the two through-movement lanes in eachapproach and a saturation flow rate of 1,900 pcphpl. A 3-phase fixed timing signal plan (namely, aprotected left-turn phase, a NS phase, and an EW phase) is suggested.I) In the diagram, the through movement volume is for 2 lanes and left tum volume is for one-lane.2) Determine one N-S or E-W left tum phase on the…an 8 lane bfs in rolling terrain has a lanr width of 12 ft right shoulder width of 8 ft one interchange every 2 ,iles. the traffic volume is 2360 veh / h which consists of 6% trucks. the peak hour factor is 0.895.

- A vehicle moving in wet weather along down grade highway of (- 4%) grade. The design speed (48mile/hr.), (f = 0.30), (t = 2.50 Sec.). The stopping sight distance you recommended is equal toEstimate the free-flow speed of a six-lane suburban freeway with 12 ft lanes, a right-side lateral clearance of 2ft,and ramp density of 3.5 ramps/mi. Normal conditions, i.e., good weather, no incidences, no work zones, andregular users of the facility, may be assumed.A signalized intersection has two lane groups. The two WBT lanes (lane group #1) have a total volume of 863 pc/h and an average control delay of 24.5 seconds. The one WBL lane (lane group #2) has a volume of 203 pc/h and an average control delay of 36.5 seconds. What is the approach's LOS? Group of answer choices LOS A LOS D LOS C LOS B
- A design control that determines the future demand of a highway and can reduce the risk of under or overdesign of a highway.A new section of Richmond Highway is being designed as a six-lane facility (three in each direction) with a two-way left-turn lane. Determine the peak-hour LOS. (Assume commuter traffic, 5% trucks, and no RVs.) Traffic data: demand volume = 3,120 veh/h PHF = 0.95 assumed base free-flow speed = 55 mi/h Geometric data: urban setting rolling terrain lane width = 11 ft shoulder widths = 4 ft (right side) and 1 ft (left side) average access point spacing = 12 points per mile on each side LOS A LOS B LOS C LOS D LOS E LOS FA new section of a freeway is to be designed with a free-flow-speed of 65 mph along of 0.75 mile on 5% upgrade. The expected traffic volume is 4200 v/hr. The traffic composition is 15% trucks, 5% recreational vehicles, and 10% buses. The peak hourly factor is 0.9, the unfamiliar driver factor is 0.95. If the design requirement is to target a level of service (B), how many lanes must be provided to satisfy the design requirement?
